IMPROVEMENT IN RAILWAY-TANK FEEDERS.

Specification forming part of Letters Patent No. 155,705, dated October 6, 1874; application filed l July 3o, 1814.

railroad-tanks with Water, in which'the wheels of a passing train act upon levers alternately for moving the pistons of pumps. This invention has for its object to render such class of apparatus more reliable and perfect in operation, and extremely simple in construction. The improvements are fully hereinafter described and pointed out in the claim.

In the accompanying drawing, Figure l represents a horizontal section on the line .fr x,

showing my invention as applied to a railroad-track; Fig. 2, a partly vertical section of the same through the line y y, looking in direction of the arrow '2; and Fig. 3 a similar sectional view through the line y y, looking in direction ofthe arrow w, and showing the track with my system of levers applied also a truck of a passing train as operating thereon.

A A represent the rails of a railroad-track 5 and Bran elevated tank, into which the water Ais required to be pumped, by the action of a passing train, for supplying, as required, the locomotives or tenders of the trains with Water. Arranged alongside the one rail, A, preferably on the outside thereof, are-two levers, C C', having their fulcrums b b near their back or outer ends, and with their inner or free ends resting on a cam composed of toes or lifters d d', attached toa rock-shaft, D, on opposite sides of the latter. The upper surfaces of the free ends of these levers are formed with double or reverse inclines o e', to provide for their action, by passing trains, in opposite directions of travel. Saidinclines project sufciently upward to be struck or borne down upon by the several Wheels of a train passing over the rail A whenever either toe or lifter d d' has been raised by the motion of the rockshaft D, as clearly illustrated in Fig. 3, either l lever C C being raised, alternately, by the depression of the other lever, whereby a nearlycontinuous rocking action of the shaft D is kept up, and each wheel, in succession, is caused to operate rst upon the one lever, and then on the other. This not only gives a quick or frequent rocking action to the shaft D, Which works the pumps E E that supply the tank B, the several wheels throughout the train on thel lever side of the track acting successively on both levers, and each wheel producing a whole double movement of the rockshaft, so that not only is a positive motion obtained for both, or reverse strokes of the plungers of the pumps, but a much larger effectthat is, a greater number of pump-strokes during the passing of -a train--thanwhem as in other apparatus for a like purpose, a counterpoise, whichl descends slowly, is used to give a return action to the pumps. I dispense,

also, with all rising and falling railsections, and keep the rails ofthe track intact, and silnplify the construction of the apparatus as a whole. f

As the levers C C are arranged in the drawing, they are actuated by the tread of the wheels G of the train, to insure which an inside guard-rail, H, may be placed within the track to prevent the wheels from passing Without rolling over.

Either or both of these levers C C are hung so as to admit of their being moved laterallyas, for instance, by hand-levers J-out of the way of the Wheels of the passing vehicles, as shown by dotted lines for the lever C in Fig. l. This isdone whenever it is necessary to allow a train to pass without operating the pumps.

I am aware that rocking levers have been provided on the side of the rail of v a railroadtrack, so that the car-wheels will depress the ends of the levers alternately for oscillating a vert-ical shaft which is connected with the horizontal shaft on which the levers are xed, said vertical shaft communicating motion to the pistons of pumps arranged horizontally on the side of the track, this being accomplished by providing the vertical shaft with pawls, Which mesh with pinions having crank arms connecting with the piston-rod of the pump, so that the said pawlsrevolve the pinions, and reciprocate the pistons.

I claim- The laterally-adjustable levers C C', pivoted at their rear ends, and provided at their opposite ends with double or reverse inclined surfaces` e e', as described, in combination with the rock-shaft D, having the toes or lifters d d on each side thereof, for alternately raising and `lowering the levers C, substantially as herein'shown and described, for directly imparting a reciprocating motion to the piston ot' a pump, as set forth.
